The Federal Communications Commission Narrowbanding Mandate requires all nonfederal radio licensees operating 25 kHz systems in the 150-174 MHz and 421-512 MHz bands (VHF and UHF) to migrate to the more-efficient 12.5 kHz (narrowband) channels by January 1, 2013.
The resources below provide information to help you plan your transition from wideband to narrowband. This list was compiled by the DHS’ Office of Emergency Communications (OEC) Narrowbanding Working Group. If you’d like to add narrowbanding resources to this list, email suggestions to the OEC.
